A command to multiply each selected Sound object by a window shape.
Suppose we have the following sound:
Create Sound from formula: "sweep", 1, 0.0, 0.1, 44100, ~ sin(2*pi*1000*x^2)
Draw: 0, 0, -1.0, 1.0, "yes", "curve"
The shape of a Hanning window is
Create Sound from formula: "window", 1, 0.0, 0.1, 44100, ~ 1
Multiply by window: "Hanning"
Draw: 0, 0, 0.0, 1.0, "yes", "curve"
If you multiply these with each other, the result will be
selectObject: "Sound sweep"
Multiply by window: "Hanning"
Draw: 0, 0, -1.0, 1.0, "yes", "curve"
In short:
Other windows:
The following one does nothing:
These two have an effective duration that is 50 percent shorter:
And these are narrower again:
